Ft. Benning is located in southeastern Georgia within the Fall Line Sandhills District of the Coastal Plain and the Piedmont physiographic provinces. Our longterm objective is to evaluate the ecological effects of military training (Figure 1) and forest management for longleaf pine at Ft. Benning, to determine if there are thresholds beyond which upland ecosystems cannot sustain the combined effects of burning and military traffic disturbances. We hypothesize that soil type (sandy vs. clayey) (Figure 2) influences nutrient cycling, species diversity, and vegetation dynamics, as well as the threshold for sustainability of land use disturbances.
